Remove Image from Registry

This tutorial shows how to remove a previously pushed image to the registry using the pure registry API or skopeo.

Prerequsities

• kubectl
• Kyma CLI v3
• skopeo (for the skopeo scenario)
• curl (for the registry API scenario)

Steps

1. Enable the image manifests deletion functionality by changing the .spec.storage.deleteEnabled flag to true:

kubectl apply -n kyma-system -f - <<EOF
apiVersion: operator.kyma-project.io/v1alpha1
kind: DockerRegistry
metadata:
    name: default
    namespace: kyma-system
spec:
    storage:
        deleteEnabled: true
EOF

Once the DockerRegistry CR becomes Ready, you see the updated .status.deleteEnabled field with a new value.

...
status:
    deleteEnabled: true

2. Push the image to the registry:

kyma registry image-import <IMAGE_NAME>:<IMAGE_TAG>

3. Port-forward the registry service to another terminal:

kubectl port-forward -n kyma-system svc/dockerregistry 5000:5000

4. Export registry credentials:

export DR_USERNAME=$(kubectl get secret -n kyma-system dockerregistry-config -o jsonpath="{.data.username}" | base64 -d)
export DR_PASSWORD=$(kubectl get secret -n kyma-system dockerregistry-config -o jsonpath="{.data.password}" | base64 -d)
